With great popularity comes great burden. Palworld has experienced this with massive influx of players when the game launched in Early Access earlier this year. The situation is much more stable now with tenth of the player count it used to have, yet that doesn’t mean that there are no problems whatsoever. One of the most painful ones can be related to losing your world, which basically acts like a game save. It usually occurs as “Unknown World Data” message on your world, not allowing you to load it. Worry not, as there is a way to fix this issue and here you will learn how to do it quickly and easily.

Unknown World Data fix in Palworld

There have been reports of players who have lost their progress in Palworld. While trying to access the game from main menu, instead of their world name, “Unknown World Data” message was shown. This indicates problems with the save file, yet there is nothing to worry about since the title has implemented a backup system to prevent data loss. All you have to do is access backups and bring back the most recent save, wasting no more than a little of your gameplay at most.

To fix the problem, you would need to access Local AppData folder for your user profile. It is a hidden folder by default located in


The easiest way to access it, however, is to press the Windows button and “R” key on your keyboard, then type or paste %LocalAppData% and press enter. Once in the Local folder, navigate to Pal directory, then Saved, and SaveGames. There you will find a folder with cryptic looking name containing many numbers, access it and another folder consisting of numbers and letters will be there. Enter it too, to find more friendly named folders, one of which will be named backup.

This whole operation can be a bit more complicated if you have more than one world. To make it easier to find the correct folder, try comparing the world and folder creation dates.

In the backup directory, you will find more catalogues with names corresponding to the date when the backup was created. Enter the most recent one and copy its contents (it should be only LocalData.sav file). Go back up several levels to the folder with sequence of letters and numbers, you will recognize it by LocalData.sav file. There, paste the one you have copied and overwrite the old save.

With all that done, you should be able to access your world without or with minimal progress loss. Also keep in mind that the production is still in the Early Access stage of its life, so it is expected that it will be still rough around the edges!
